Iridoide, X: Stereospezifische Synthese von Iridoid‐α‐glucosiden
Chemische Berichte, 1978Iridoids, X: Stereospecific Synthesis of Iridoid‐α‐glucosidesTreatment of the iridoidaglycone 3 with 1,2‐anhydro‐α‐D‐glucopyranose triacetate (Brigls anhydride, 4) in the presence of a trace of boron trifluoride/ether led stereospecifically to the α‐glucosides 7, 8, and 9, with 38% yield. In an analogous reaction 10 was formed from 2.
